Duolingo vs Preply is a choice between two different products: a free app that drills words and sentences, and a marketplace of paid tutors who make you talk. If you're squeezing practice around a job, a trip or a move, the useful question is what each one does for your speaking, and when the app on its own is enough.
Every rule and price below comes from the US App Store listing, Duolingo's Help Center and the Preply Help Center, checked on 28 September 2026.
How are Duolingo and Preply different?
Duolingo is a self-study app: you tap through short themed lessons, earn streaks and follow a path set by the course. Preply connects you with a human tutor for live 1-on-1 video lessons, where you choose the tutor, the topics and the pace. One trains recognition and habit, the other trains you to answer a real person.
| Checked September 2026 | Duolingo | Preply |
|---|---|---|
| What you do | Short game-like exercises | Live video conversation with one tutor |
| Speaking practice | Say sentences to the app; AI Roleplay and Video Call with Max | Most of the lesson, if you ask for it |
| Who corrects your mistakes | The app, against expected answers | The tutor, on what you actually said |
| Schedule | Any time, 5 to 15 minutes | Booked slots, 25 or 50-minute lessons |
| Price model | Core lessons free with ads; Super from $9.99 to $119.99 | Paid trial, then a subscription billed every 28 days |
| Languages | More than 40 | English, Spanish, French, Italian and many more |
| Best for | Vocabulary, habit, a first taste of a language | Speaking, a deadline, a specific goal |
Verdict: Duolingo is the cheaper habit, Preply is the one that puts a person on the other end of the sentence.
Can Duolingo alone teach you to speak a language?
Duolingo alone can get you saying simple sentences out loud, but it can't give you an unscripted conversation. The app checks your answer against what it expects, so you never have to explain your weekend, defend an opinion or recover when someone asks "why?". That recovery is the skill conversation needs.
Duolingo does several things well. Its blog says its major courses are aligned with the CEFR, the Council of Europe's six-level scale (A1 to C2), and it offers a free path in more than 40 languages. The streak keeps people practising on days they would otherwise skip, which counts for a lot at beginner level.
What does Duolingo Max add for speaking?
Duolingo Max is the top subscription. According to Duolingo's Help Center, it includes everything in Super Duolingo plus two AI features: Roleplay, where you follow a scenario with an app character, and Video Call with Lily. Max is sold in the iOS and Android apps, not on the web. These are real speaking drills, but the partner is software, not a tutor who knows your goals.

When is Preply worth paying for instead of Duolingo?
Preply is worth paying for when you need to speak by a date: a job interview, an exam, a move abroad, or a stall at intermediate level where apps stop helping. A Preply tutor corrects what you actually say and adapts the next lesson to your mistakes, which no app course does.
Four situations where a tutor is the better use of money:
- You have an exam with a speaking part, such as IELTS or DELE.
- Your job now requires meetings, calls or clients in the language.
- You're moving and need to handle a landlord, a doctor or a school.
- You understand a lot but freeze when you have to answer.
The last one was my case. I'm learning English on Preply with my tutor Ken, and my level is B1, aiming for B2+. My reading and listening were already good; expressing myself out loud was the problem. I credit my fast progress to speaking for most of every 50-minute lesson. If your job is the reason, our page for working adults learning a language lists the situations worth rehearsing first.
What are Preply's real downsides compared with Duolingo?
Preply's biggest downside is the commitment. The Preply Help Center says each subscription is tied to one tutor, runs in 28-day cycles with a minimum of 4 lessons, and unscheduled lessons expire at renewal. Duolingo never charges you for a lesson you skipped. You can pause a Preply subscription once per cycle for up to 20 days, but you have to remember to do it.
The trial is paid too. Each trial lasts 25 or 50 minutes, and if it disappoints, you can ask for up to 2 free replacement trials with other tutors per account. My full account of the booking and the costs is in the Preply review.
How much does Duolingo cost compared with Preply over a year?
Duolingo costs nothing if you accept ads, and Super Duolingo in-app purchases on the US App Store range from $9.99 to $119.99 (checked September 2026). Preply costs whatever your tutor charges, times at least 4 lessons, times 13 billing cycles a year, because Preply bills every 28 days rather than monthly.
| One year, checked September 2026 | Lessons | Cost |
|---|---|---|
| Duolingo, free with ads | Unlimited app lessons | $0 |
| Super Duolingo, highest App Store price | Unlimited app lessons, no ads | $119.99 |
| Preply, 4 lessons per cycle at an example $20 rate | 52 live lessons | About $1,040 |
| The author's plan on Preply (12 hours a month at about €34) | About 144 hours of live lessons | About €4,900 |
Verdict: even the paid app costs about a ninth of one modest weekly lesson plan, but it can't correct your speaking; the tutor is what you pay for being corrected.
The $20 rate is an example, not an average: tutors on Preply set their own prices, and cheaper and pricier tutors exist in every language. My own figure is real: 12 hours a month at about €34 an hour, roughly €408 a month in September 2026. If you're weighing tutoring sites on price, the Preply vs italki comparison explains how pay-per-lesson billing changes the math.

How do you combine Duolingo and Preply in one week?
Duolingo and Preply work best together when each one has a separate job: the app for words and review on the days without a lesson, the tutor for speaking with those words. A week built this way costs one lesson plus the free app, and no minute of the lesson goes to drills you could do alone.
- Book one weekly Preply lesson at a fixed time, 50 minutes if you can, 25 if not.
- On three or four other days, do 10 to 15 minutes of Duolingo on the same theme.
- Before each lesson, write five sentences about your week using the new words.
- In the lesson, say them to the tutor and ask to be corrected every time.
- Once a week, practise out loud with a voice assistant for a few minutes.
I do step 5 in the morning with ChatGPT's voice mode, while stuck in traffic. It doesn't replace Ken, but it means I arrive at the lesson having already said the sentences once. Not sure what level to tell a tutor? The level quiz gives you a CEFR estimate in two minutes.
Skip paid tutoring for now if you can't protect one slot a week: a subscription that renews while you cancel lessons costs more than it teaches. Use free Duolingo and a weekly language exchange until your schedule settles. For a Speakly angle on the app side, see our Speakly vs Duolingo guide.
Questions people ask about Duolingo and Preply
Is Preply better than Duolingo?
Preply is better for speaking, because a tutor listens to you, corrects you and makes you rephrase. Duolingo is better for a free daily habit and for vocabulary in more than 40 languages. They solve different problems, so many learners keep the free app and add a tutor once a week.
Can Duolingo make you fluent?
Duolingo alone rarely gets you to fluent conversation, because the app decides what you say and nobody asks you an unexpected follow-up question. Duolingo says its major courses are aligned with the CEFR, and it can take you through beginner and lower intermediate material. Speaking fluently still needs practice with people.
Is Preply worth it for complete beginners?
Preply is worth it for beginners who can book one lesson a week, because a tutor fixes pronunciation and basic mistakes before they become habits. If your budget or schedule doesn't allow a weekly slot yet, start with free Duolingo for a month and book a 25-minute trial once you know the basics.
How much does Preply cost compared with Duolingo?
Duolingo's core lessons are free, and Super Duolingo in-app purchases range from $9.99 to $119.99 on the US App Store (checked September 2026). On Preply, tutors set their own rates and you pay a subscription of at least 4 lessons per 28-day cycle, so a weekly lesson costs 13 times the tutor's rate over a year.
Does Duolingo have real teachers?
No. Duolingo's lessons and its speaking features are automated. Duolingo Max adds Roleplay and Video Call, which are conversations with AI characters such as Lily, not with a human teacher. If you want a person to correct you, you need a tutor, a class or a language exchange partner.
Should I use Duolingo and Preply at the same time?
Yes, if you give each app and tutor a different job. Use Duolingo for 10 to 15 minutes on the days without a lesson to review words, and use the Preply lesson to speak about your own life with those words. Tell your tutor what you studied so the lesson builds on it.
